The front end ol said plug cock 35 `is provided with a threaded stem 38 for receiving a threaded sleeve 39, said sleeve 39 being adapted to be received in a recess l0 in said body portion 4 for the purpose ol.z holding the plug cock 35 in position. The extended end of the stem 33 is provided with a handle 4l for nfianipulating the plug cock. Said plug cock 35 is provided with a bore 42 extending completely therethrough, and a secondfbore 43 at right angles thereto extending through one face only ot said plug cock 35. Said bores ,49. and 43 are thus arranged in the i'orni of a T, as is common in three-way cocks.y The barrel of said plug cock 35 is further provided with a recess ai in its face opposite the bore 43. ,As shown in Figure l said recess 4st is adapted to register with the outlet passage 26 and the offset passage 3l when theplug cockis in one position. In thatposition the bore 43 registers with the inlet passage Q5 and forms with the bore l2 a continuons passage into the tube 33. In this position, therefore, gas entering the inlet passage will How down through the tube33 into the luid 3 in the gas washing bottle 2. The washed gas will, ot course, bubble up to the surface of the iluid 3 and escape through the neck ol the bottle into the offset passage 34, which, as has been explained, is in unrestricted communication with the outlet passage 26.

In the second position of the plug cock 35, as shown in Figure 5, the bore 49. forms acontinuous communication with the inlet and outlet passages 25 and E26, respectively, and the bore 43 is in inoperative position. Accordingly the gas entering the inlet pas sage 25 is bypassed over the tube 33. It will be noted that the oliset passage 3st is partially `open when theplug cock is in this position, but this would have no eil'ect l'ar as the by-passing of the gas is concerned, since the gas washing bottle 2, being already lilled above the Huid 3 with gas or air, there is little or no tendency of the gas to pass downwardly through the passage 34. In order to limit the movement of the plugr cock 35 there is provided a pin 4:5 cxtending inwardly from the inner face ol the spherical head 36 and adapted to move in a groovewlt formed in the valve body portion 4. Said groove t6 is so positioned and of: such length as to limit the movement of the pin to an are of 90. The pin l5 therefore limits the rotation of the plug cock 35 in one extreme position to the position shownin Figure 1. and in the other extreme position to that shown in Figure A marker Il? on the periphery of the handle 41 indicates at what position the plug cock may be. y

It is thus apparent thatl l have provided a simple and compact by-pass valve that is peculiarly adapted for use with gas washing apparatus. valve such as described is much more satisfactory than the usual type of three-way cock and is more serviceable than glass plug cocks such as are ordinarily used in laboratory work.

.l am aware that many changes may be made, and numerous details of construction may he varied through a wide range without departing l'rom the principles ol' this invention, and I therefore do not purpose limiting the patent granted hereon, otherwise than necessitated by the prior art.

I claim as my invention:

l. A by-pass valve tor gas washing apparatas, comprising a body portion adapted to be mounted on a receptacle containing a washing iluid, said body portion having aligned horizontal inlet and outlet passages, a central downwardly extending passage and an oli'set passage parallel to said central passage and in open communication with said outlet iiassage, a tube secured in said central passage and adapted to extend below the surface of the fluid in said receptacle, and a plug-cock for said body portion having 3- way bores therein, said bores in one position of said plug-cock being adaptedto establish communication between said inlet and outlet passages to by-pass the gas around the receptacle and in another position to establish communication between said inlet passage and said central passage whereby the gas is caused to pass through said tube into `the fluid in the receptacle, the undissolved gases escaping through said ollset passage into said outlet passage.

2. In combination, a by-pass valve having a lower flanged portion adapted to be mount-` ed upon a container in the washing apparatus and an upper projecting lug, a clamp adapted to be secured to the container, a cross bar adapted to contact said lug, and tightening means joining said cross bar and clamp to clampingly secure said valve to said container,

3. In combination, a by-pass valve adaptlUu llt)

ed to be mounted on the top of a neck pori tion of a container, and a tube connected to said valve and Vextending downwardly through said neck portion and into a liquid in the container, said valve including an inlet adapted to be connected lo said tube to deliver gas into said container` and an outlet connected to the interior of the said neck portion of said container for discharging the gas from the container after it has passed through said liquid.

Al. In combination, a by-pass valve adapted to be mounted on the top oi a neck portion ol a container, a tube connected to said valve and extending downwardly through said neck portion and into a liquid in theco1itai11er,said valve including an inlet adapted to be connected to said tube to deliver gas into said container, and an outlet connected to the interior oit the said neck portion of said con tainer for discharging the gas from the container after it has passed through Said liquid, said `valve having a body including a flange cooperable with the flange on the upper end of the neck portion of the. container, and means for clamping said flanges together comprising a pair of cooperable clamp ineinbers disposed about said flanges and detachably anchored to each other.

5. In combination, a by-pass valve adeptled to be Inounted on the top of a neck portion of a container, and a tube connected to said Valve and extending downwardly through said neck por-tion and into a liquid in said container, the Valve including an inlet adapted to be connected to said tube to deliver gas into Said container, and an outlet connected to the interior of the said neck portion o'f said container for diecl'iarging the gas from the container after it has passed through said liquid, said valve including a three-way rotatable cock, said Avalve having a passageway connnunicating with. one ot the openings in the cock, telescoped by the end olf' said tube.
